Description and Introduction

Standalone Linear Li-Ion Battery Charger with Thermistor Input The LTC4061EDD#PBF is a battery charger IC manufactured by Linear Technology (now part of Analog Devices). Here are its key specifications, descriptions, and features:

### **Specifications:**
- **Input Voltage Range:** 4V to 6.5V  
- **Charge Current:** Programmable up to 1A  
- **Battery Voltage:** 4.2V (for single-cell Li-Ion/Polymer)  
- **Charge Termination:** C/10 or Timer-Based  
- **Precision Charge Voltage:** ±0.6%  
- **Operating Temperature Range:** -40°C to +85°C  
- **Package:** DFN-8 (3mm × 3mm)  

### **Descriptions:**
- Standalone linear battery charger for single-cell Li-Ion/Polymer batteries.  
- Features thermal regulation to optimize charge rate without overheating.  
- Includes automatic recharge and charge status indication.  
- No external MOSFET, sense resistor, or blocking diode required.  

### **Features:**
- **Programmable Charge Current:** Up to 1A with a single resistor.  
- **Thermal Regulation:** Reduces charge current if die temperature exceeds 115°C.  
- **Charge Termination Options:** Selectable between C/10 or timer-based.  
- **Automatic Recharge:** Initiates charging if battery voltage falls below 4.1V.  
- **Status Outputs:** Indicates charging (CHRG pin) and charge completion (DONE pin).  
- **Low Battery Detection:** Optional feature with an external resistor divider.  
- **Battery Reverse Protection:** Prevents damage if battery is inserted incorrectly.  

This IC is designed for portable applications requiring compact and efficient Li-Ion/Polymer battery charging.
